South Korea not seeking collapse of North Korea

South Korean President Moon Jae In called on Thursday (Sept 21) for the North Korean nuclear crisis to be handled in a stable manner, so that peace was not destroyed.

Moon said he highly appreciated the recent UN Security Council resolutions against North Korean's "provocations" and said the body's swift action showed the global community was "collectively outraged" by Pyongyang's actions.

The additional sanctions on Pyongyang showed that Trump was giving more time for economic pressures to weigh on North Korea after warning about the possibility of military action on Tuesday in his first speech to the United Nations.

The timing of the assistance, however, has not been set as the government plans to take into account current inter-Korean relations.

The U.N. agency UNICEF estimates 5.3 million children and pregnant women in North Korea need humanitarian assistance.

"We have consistently said we would pursue humanitarian aid for North Korea in consideration of the poor conditions children and pregnant women are in there, apart from political issues", said Unification Minister Cho Myong-gyon.

North Korea conducted its sixth and largest nuclear test on 3 September and has launched numerous missiles this year, including two intercontinental ballistic missiles and two other rockets that flew over Japan.

A United States official said that Trump would later Thursday make an announcement of further sanctions on North Korea.

"The situation surrounding the North Korean nuclear issue needs to be managed stably so that tensions will not become overly intensified or accidental military clashes will not destroy peace", Moon said.

Trump also mocked its leader, Kim Jong-un, calling him a "Rocket Man".
